How to add keyframes to a rig?
If you go in the Properties panel &gt; Object &gt; Transform panel, whether you've selected the object or the whole armature in Object mode, you'll keyframe the object or the whole armature, not the bones.
If you want to keyframe the bones you need to select the armature, switch to Pose mode, move the bones, let your cursor in the 3D View, and press i to save.
Don't forget to remove all the animations you've created for the whole armature and object.
